Windows 7: Cannot Boot from USB disk

I try to install a fresh copy of win7 on my Acer laptop but cannot boot from usb disk. I did everything, boot order, legacy, bios update etc. I've even tried UEFI bootable disk. Still cannot boot from usb disk, its directly load the windows 7. What would be the problem?

Set DVD drive first to boot, HD second, set SATA controller to AHCI, Save changes and Exit.

Then boot into Windows 7 installer DVD or flash stick burned or written using tool and latest ISO for your licensed OS version here. I would use a fresh ISO written with tool in Step 2 as yours is in question.

After install you can adjust partition size or Create new partitions for data, etc. in Disk Mgmt. You are creating the partition here for the purpose of wiping the HD and marking Active which overcomes certain install failures.

Once you have a good flash stick installer, reboot and tap the Acer F12 key for BIOS Boot Menu, select Flash stick to boot under USB, Removable or HD's. You may need to expand one of those listings to see the stick.

If this fails see if you can boot the stick in another PC. If so then enter BIOS setup on the Acer to see if there are any USB settings that needs adjustment. If in doubt ask back here about a setting providing a camera snap if possible. You must Save any changes before exiting BIOS.
